This is a technical drawing and Bill of Materials (BOM) document for a Compressed Air System Piping Diagram Modification (AS-Built) for the National Oceanic and Atmospheric Administration (NOAA) Office of Marine and Aviation Operations.

The document provides detailed specifications for compressed air system piping modifications, including a comprehensive list of materials and quantities required for the ship installation. The BOM identifies over 80 line items encompassing pipe fittings, valves, pressure relief valves, unions, elbows, tees, and associated hardware in various sizes and materials (primarily steel and bronze). Specifications reference ASTM standards for materials, including ASTM A53, ASTM A75, and other applicable standards. The document includes general notes addressing installation requirements, material certifications, inspections, and system testing procedures. Technical drawings across two pages illustrate the piping layout with elevation views, sections, and plan views showing the spatial arrangement of components, connections, and pressure relief systems. The design specifications indicate requirements for various pipe sizes ranging from 1/4" to 2", with materials specified as steel or bronze depending on application. The document is identified as drawing number TJ-551-002, sheet 1 of 2, and includes revision tracking information.
